Abstract
Description
Die Erfindung betrifft ein Vitaldiagnose- und Überwachungsgerät zur Überwachung wenigstens der Herzfunktionen, mit einer füllerartig ausgebildeten Sonde, die mit wenigstens zwei voneinander beabstandet am Umfang der Sonde angeordneten Elektroden versehen ist, und einer Einrichtung zum Anzeigen der von der Sonde erfassten, einen Rückschluss auf Vitalfunktionen erlaubenden Signale.The invention relates to a vital diagnosis and monitoring device to monitor at least the heart functions, with a filler-shaped probe with at least two spaced from each other on the circumference of the probe Electrodes is provided, and a device for displaying the detected by the probe, a conclusion on vital functions allowing signals.
Aus der DE 36 36 996 C1 ist ein Herzdiagnosegerät bekannt, das füllerartig ausgebildet ist und an seinem Umfang mit wenigstens zwei Elektroden versehen ist. Dieses Herzdiagnosegerät dient dazu, im Notfall dem behandelnden Arzt eine Aussage über die Herzfunktion des Patienten zu erlauben.A cardiac diagnostic device is known from DE 36 36 996 C1 is filler-like and on its circumference with at least is provided with two electrodes. This heart diagnostic device is used In addition, in an emergency, the treating doctor a statement about the Allow patient heart function.
Das Gerät ist insofern unzulänglich, als es für eine länger andauernde Überwachung ungeeignet ist.The device is inadequate in that it lasts for a longer time continuous monitoring is unsuitable.
Der Erfindung liegt die Aufgabe zu Grunde, ein Vitaldiagnosegerät der eingangs genannten Art zu schaffen, das eine Notfallüberwachung erlaubt.The invention is based on the object of a vital diagnosis device to create the one mentioned Emergency monitoring allowed.
Erfindungsgemäß wird diese Aufgabe gelöst durch eine ein Einführen in die Speiseröhre erlaubende Sonde zur Erfassung aller für eine Überwachung erforderlichen Funktionen, die über ein Kabel mit einer außerhalb des Patienten verbleibenden Auswerte- und Anzeigeeinrichtung verbunden ist.According to the invention, this object is achieved by a Inserting probe into the esophagus for detection all functions required for monitoring that are available via a cable with one remaining outside the patient Evaluation and display device is connected.
Eine bevorzugte Ausführungsform eines Diagnosegerätes gemäß der Erfindung ist gekennzeichnet durch eine flexible, ein Einführen in die Speiseröhre erlaubende Ausgestaltung, wobei die Sonde über ein Kabel mit der gesondert ausgebildeten, außerhalb des Körpers des Patienten verbleibenden Auswerte- und Anzeigeeinrichtung verbunden ist, und die Sonde mit einem Temperatursensor, einem Sensor zur Erfassung der Sauerstoffsättigung, einem zur Erfassung der Herztöne und der Atemgeräusche dienenden Schallsensor und mit einem zur Erfassung der pulssynchronen Blutbewegungen dienenden Doppler-Schallkopf versehen ist, der seine Umgebung segmentweise über einen Raumwinkel von 360° abtastet und dass in der Auswerte- und Anzeigeeinrichtung dasjenige Raumsegment ausgewertet und angezeigt wird, das das kräftigste pulssynchrone Flüssigkeitsströmungssignal liefert.A preferred embodiment of a diagnostic device according to the Invention is characterized by a flexible, an insertion design allowing in the esophagus, the probe via a cable with the specially trained, outside the Body of the patient remaining evaluation and Display device is connected, and the probe with a Temperature sensor, a sensor for detecting the Oxygen saturation, one for recording the heart sounds and the Sound sensor serving breathing noises and with one for recording the Doppler transducer, which serves to synchronize blood movements is provided, which its segment by segment over a Solid angle of 360 ° scans and that in the evaluation and Display device evaluates that room segment and is displayed, which is the strongest pulse-synchronous Liquid flow signal provides.
Das erfindungsgemäß ausgebildete Vitaldiagnosegerät ist vor allem für den Notfalleinsatz innerhalb und außerhalb der Klinik gedacht. Der Notfallarzt (oder auch das medizinische Assistenzpersonal) führt die Sonde in die Speiseröhre ein und aktiviert diese über das mit der Sonde über ein dieses haltende und die elektrische (ggf. auch fluidische) Kommunikation herstellendes Kabel. Die Anzeigeeinrichtung ist dazu eingerichtet, die von der Sonde erfassten Vitalparameter in geeigneter Form anzuzeigen.The vital diagnostic device designed according to the invention is in front especially for emergency use inside and outside the clinic thought. The emergency doctor (or the medical one Assistants) introduces the tube into the esophagus and activates this via the one holding the probe and electrical (possibly also fluidic) communication manufacturing cable. The display device is for this set up, the vital parameters recorded by the probe in appropriate form.
Der Vorteil des Gerätes besteht darin, dass es auch in Extremsituationen, wie großer Kälte, Feuchtigkeit, Dunkelheit, einer unruhigen Umgebung oder eines unruhigen Patienten sowie bei einer extrem schlechten Kreislaufsituation, bei der die üblichen Messverfahren versagen, die Erfassung von Vitalfunktionen erlaubt.The advantage of the device is that it is also in Extreme situations, such as extreme cold, moisture, darkness, an uneasy environment or an uneasy patient as well in an extremely bad circulatory situation in which the usual measurement methods fail to capture Vital functions allowed.
Bei dem bevorgzugten Diagnosegerät gemäß der Erfindung wird
Abhängig von der Tiefe, in die die Sonde in die Speiseröhre vorgeschoben wird, könnte auch die linke Herzkammer benachbart zu der Speiseröhre liegen, welche auch ein deutliches andersartiges Strömungsprofil liefern kann.Depending on the depth at which the tube enters the esophagus advanced, the left ventricle could also be adjacent to the esophagus, which is also a distinctly different one Can provide flow profile.
Es gilt, mittels des Schallkopfes oder der Schallköpfe das Segment auszuwerten, welches das kräftigste pulssynchrone Flüssigkeitsströmungssignal liefert. Dieses Signal soll qualitativ bewertet zur Anzeige gebracht werden, weil es eine Aussage über die Pumpfunktion des Herzens (keine, geringe, mäßige, kräftige, ... Pumpfunktion) liefert.It is important to use the transducer or transducers to evaluate the segment that delivers the strongest pulse-synchronous liquid flow signal. This signal should be displayed with a qualitative rating because it provides information about the pumping function of the heart (no, low, moderate, strong, ... pumping function).
Diese Aussage hat unmittelbare Behandlungskonsequenzen für den kritsch Kranken und ggfs. reanimationspflichtigen Patienten. Erst durch Kombination mit EKG-Signal und Pulsoxmetrie über die gleiche Sonde lässt sich die Lebensbedrohung, die auch wiederum von der Kerntemperatur abhängig ist, ableiten.This statement has immediate treatment consequences for the critically ill and possibly resuscitated patients. Only when combined with an ECG signal and pulse oximetry via the same probe can turn the life threat, which in turn depends on the core temperature.
Alle diese Messungen werden in der Speiseröhre noch verlässliche Signale liefern, wenn an der Körperoberfläche dies bereits nicht mehr möglich ist. Eine Auswertung des EKG-Signals kann dahingehend erfolgen, festzustellen, ob die Sonde in die korrekte Tiefe vorgeschoben ist.All of these measurements become more reliable in the esophagus Deliver signals when this is not already on the surface of the body is more possible. An evaluation of the EKG signal can to determine whether the probe is in the correct depth is advanced.
Das angeschlossene mobile Signalverarbeitungs- und anzeigegerät wird die Signale bewerten und verknüpfen. Die Qualität der Vitalfunktionen des kritisch erkrankten Menschen lässt sich unmittelbar und bewertet hinsichtlich der Signalqualität ablesen,The connected mobile signal processing and display device will evaluate and link the signals. The quality of the Vital functions of critically ill people can be read directly and evaluated with regard to the signal quality,
